It's interesting: one absence of parallel seems significant, of course, that there is no weapon you can scapegoat in a rape. Nobody can use it as a pretext for demanding "penis control", trying to ban penises they think are extra-dangerous by branding them "assault penises", or demanding a week's delay before you can use a penis.
I think having one of the rapes actually happen right in the police station itself goes a long way to explaining the uproar: when rapes can take place almost literally under the noses of the police, they clearly aren't doing a good job of fighting it. (There's a small parallel there - someone recently pointed out that one of the two murders carried out in the US with legally-held automatic weapons since they were almost entirely banned was actually committed by a cop.)
